Answer:
x=9
Step-by-step explanation:
2x+3(6)=36
2x+18=36
2x=18
x=9
Answer:
x=9
Step-by-step explanation:
if y=6 its now 2x + 18 =36. Subtract 18 from both sides. 2x = 18. 2(9) = 18. Therefore x=9

A tree outside Ellie’s house cast of 125 foot shadow. At the same time of day, Ellie cast a 5.5 foot shadow. If Ellie is 4‘10“ tall, how tall is the tree in feet?
Answer:
The tall of the tree is about 109.85 feet
Step-by-step explanation:
- The tree and its shadow formed a right angle triangle with legs
x the tall of the tree and 125 feet the shadow of the tree
- Ellie and her shadow formed a right triangle with legs 4 feet and
10 inches the tall of Ellie and 5.5 feet the shadow of Ellie
- The two triangles are similar
- There is an equal ratio between the corresponding sides of the
similar triangles
∵ The tall of the tree is x
∵ The tall of Ellie is 4 feet and 10 inches
babyface17
∴ The tall of Ellie is 4 feet and 5/6 foot = 4 + 5/6 = 29/6 feet
∵ The shadow of the tree is 125 feet
∵ The shadow of Ellie is 5.5 feet
- By using similarity ratio
∴ Tall of tree/tall of Ellie = shadow of tree/shadow of Ellie
∴ x/(29/6) = 125/5.5 ⇒ using cross multiplication
∴ 5.5(x) = 125(29/6) ⇒ divide both sides by 5.5
∴ x ≅ 109.85 feet
* The tall of the tree is about 109.85 feet
Answer:
109.85 ft
Step-by-step explanation:
5.5'/ 4'10"=125 ft/x
5.5*12/(4*12+10)=125/x
66/58=125/x
x=125*58/66
x=109.85 ft

Which statement is true about the green,orange,and gray triangles show in the textile pattern below?
A. They are congruent obtuse triangle
B. They are congruent right triangle
C. They are acute right triangle
D. They are similar right triangle
Answer:
b
Step-by-step explanation:
the triangles are all the same so they are congruent. They are also right triangles so they must be a right triangle the only answer that combine this is b
The green, orange and gray triangles are congruent and right triangles. Thus option B is correct.
What are congruent triangles and right triangle?Two triangles are congruent triangles if they are of same size and shape.
Right triangle is a triangle with one of angle 90°.
The given triangles of green, orange and gray triangles are of same shape and size . Therefore we can say that they are congruent triangles
Also we can see that they all have right angle on the left corner therefore they are right triangles . If they are right triangles then they will be also acute triangles too as the some of other two angles of each triangle will be 90 it means they both are less than 90 and congruent means they are similar too as similar triangles have same shape.
Therefore the most appropriate option is Option B , that given triangles are congruent right triangles.

Is 7 a factor of 56w - 7?
Answer:
yes it is
Step-by-step explanation:
Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. ... The prime factors of a number or an algebraic expression are those factors that are prime.
Numbers we can multiply together to get another number.
Example: 2 and 3 are factors of 6, because 2 × 3 = 6
A number can have MANY factors!
Example: What are the factors of 12?
• 3 × 4 = 12, so 3 and 4 are factors of 12
• 2 × 6 = 12, so 2 and 6 are also factors of 12
• and 1 × 12 = 12, so 1 and 12 are factors of 12 as well
So 1, 2, 3, 4, 6 and 12 are all factors of 12
And -1, -2, -3, -4, -6 and -12 also, because multiplying negatives makes a positive.
In Algebra, factors can be expressions like "x+3" etc

Triangle G F H is rotated to form triangle G prime F prime H prime. Which type of transformation maps triangle GFH onto triangle G'F'H'? translation reflection rotation dilation
Answer:
Rotation
Step-by-step explanation:
The type of transformation maps triangle GFH onto triangle G'F'H' will be; Rotation.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs.
We are given that Triangle GFH is rotated to form triangle G prime F prime H prime.
Stretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]
Horizontal stretch by a factor k: [tex]y = f\left(\dfrac{x}{k}\right)[/tex]

What is an Angle?An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.
An angle is a figure in Plane Geometry generated by two rays or lines that share a common endpoint. The term "angle" is derived from the Latin word "angulus," which meaning "corner".
We have m < AVC = 39
and, m <VCB = 23
Thus, by adding the above angle we get the whole angle AVB.
Sp. m< AVB = m <AVC + <VCB
m <AVB = 23 + 39

Step-by-step explanation: My Explanation to this is:All triangles add to 180° so...Add all the angles in the triangle.
Find the amount missing to make an overall of 180 degrees.
85+33=118 degrees
We are currently missing angle which is 62 degrees.
How ever to find the second missing angle you will need this angle (62) specifically.
because it is on a straight line, take 62 away from 180 to get 118 degrees
the answer is 118 degrees hopefully this helped you
Answer:
Step-by-step explanation:
Exterior angle equals the sum of opposite interior angles
∠DAB = ∠ABC + ∠ACB
= 85 + 33
∠DAB = 118°

Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )

If the height is changed to 3, does this have the same effect on the volume as changing the radius to 1?
If the height is now 3, then the new volume is π units3.
If the radius is now 1, then the new volume is π units3.
Therefore, changing the height to half of its original value and changing the radius to half of its original value does the volume. Halving the height of the cone the volume, while halving the radius of the cone results in the volume.
Answer:

pleeeeeez mark brainliest
Halving the height of the cone halves the volume, while halving the radius of the cone results in 1/4 the volume.
How to find the volume of a cone?
We are given a right cone with;
radius = 2
height 6
volume is; V = ¹/₃π(2)²6 = 8π units³
If the height is now 3, then the new volume is;
¹/₃π(2)²3 = 4π units.
If the radius is now 1, then the new volume is;
¹/₃π(1)²6 = 2 units.
Therefore, changing the height to half of its original value and changing the radius to half of its original value does not have the same effect on the volume. Halving the height of the cone halves the volume, while halving the radius of the cone results in 1/4 the volume.
